-
-A layer to isolate windows.h from other source files while retaining the ability to set thread priorities.
-
-	One possible way to call it if you don't need to store the result is like so:
-
-		#ifdef _WIN32
-				bool SuccessStatus = BoostThreadPriorityToHighest();
-				if (!SuccessStatus)
-				{
-					ASSERT_M(0, "Failed to set thread priority to highest.");
-				}
-		#endif
-
-Please refer to the Windows SetThreadPriority function documentation for more information.
-https://learn.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-setthreadpriority
-
-Please maintain this priority structure for the threads:
-
-Highest or Time Critical
-* Rendering thread
-* Audio mixing thread
-	- If this is not high enough priority, it can negatively affect the game clock
-
-Above Normal or Highest
-* Audio decoding thread
-* Audio streaming thread
-* Audio buffering thread
-
-Normal
-* Main game thread
-	- Please keep this below the audio thread priority
-
-Below Normal
-* Worker threads
-
